Abstract

Abstract

The efficient recovery of metal elements from waste batteries not only makes waste resources, but also helps the battery industry to form a dynamic and sustainable cycle of manufacturing, use and recycling, and reduces the harm to the ecological environment. The study found that there was a certain amount of aluminum ions in nickel salts, cobalt salts or cathode materials during the recycling and reuse of waste batteries, which affects the purity of scarce metal elements. The secondary utilization of high priced metals requires reducing the aluminum content to 0.2%. In this paper, ultrasonic separation-color selection-shaking table re-election combined process is used in the pre-treatment stage of batteries to remove aluminum metal from waste batteries. The experimental results show that this method can reduce the aluminum content of raw materials from 1.75% to 0.18%, effectively remove aluminum from waste batteries, and improve the efficiency of waste battery recycling process.
